How to shoot fast with a slow camera

That's just a bit stupid. Doing AF and pulling back the clutch to find.. oh, out of focus. Well no sh!t Sherlock. The manual focus position will be where you last left it, it doesn't magically spin round when you're in AF.

I've pretty much stopped using my legacy lenses, having sufficient system lenses to cover my needs. If any of the XF lenses fell short in any way, I would still be using an old MF equivalent, but every Fuji is better than any of my legacy lenses.
